ATTACHMENT FOR CONNECTING COIL-SPRINGS.

SPECIFICATION forming part of Letters Patent No. 325,818, datedSeptember 8, 1885.

Application filed March 27, 1885. (No model.)

To all whom it may concern:

Be it known that I, CHARLES OARLETON, a citizen of the United States,and a resident of Lake township, Cook county, and State of Illinois,have invented a new and useful Improvement in Attachments for ConnectingSpiral Springs for Bed-Bottomsand other Purposes, reference being had tothe annexed drawings, illustrating the invention, in which- Figure 1 isa plan or top view of a section of the springs of a coil-springbed-bottom combined with myimproved attachment. Fig. 2

is a sectional edge view of one of the attachments with transversesections of the springs connected by it. Fig. 3 is a plan view of theblank attachment as it is cut from sheet metal and before it is attachedto the springs. Fig. 4 is a perspective view of the under side of theattachment shut together as when con necting the springs.

The object of the present invention is to provide simple, cheap, andsafe attachments for connecting coil-springs which are used for beds,seats, mattresses, and other purposes. Heretofore wire links have beenused for this purpose, and webbing has also been used and the laps heldtogether by metal clamps; also, metal straps have been employed andtheir lapped parts riveted together, and wires have been made to engagethe spring and run diagonally across the bed-bottom; and it has been thecustom to connect springs by straps of fabric and clamps, the latterbeing cut in a cruciform shape and the wings folded on opposite sides ofthe center a thereof to clamp the fabric in place where the strips crosseach other.

My purpose is to make a bed-bottom, mattress, or seat body wholly ofmetal, and to connect the springs by an attachment which will permit anynumber of springs to be compressed without the attachments acting aslevers on the other springs, and at the same time hold the springs agiven distance apart. This I accomplish by an attachment which is formedof a single piece of sheet metal consisting of a central body part withfour projecting wings, two of which are looped around the springs, andthe other two shut onto the looped part, whereby the attachment formsjoints on the springs.

A, &c., represent a section of six springs of the ordinary hour-glassconstruction, which when used in this form both ends are to be connectedwith my attachments and used for beds, lounges, or seats without a frameattachment. My attachments, however, may be used to connect the endsonly of the tops of the springs, and thus be employed in connection withwooden slats or frames. The blank for the attachment as cut and beforeconnected with the springs is shown in Fig. 3, and consists of a centralbody, a, two end wings, b b, and two side wings, c c. Tlieend wings arelooped over the springs A, and brought flat on to or parallel with thebody part a, and then the side wings are brought over to lie flat on theends of the wings b b, and the connections are complete.

The advantage of this attachment, aside from the points mentioned,consists in the stiffness of it between the springs, and in that itserves both the purpose of two joints and a strut to hold the springsthe required distance apart, and is preferable to a double loop forconnecting the springs, and atransverse clamp to hold the ends of theloop to its bar, a construction I have used in lieu of the one herepresented.

I claim as new ters Patent- The combination of the coiled wire springswith the connecting-plate having the wings b, which are looped over thecoils of the springs to hold them together, and the wings a, bent overthe wings b to hold them and to keep the springs separated,substantially as described.
